Installation

Jalco UI components are distributed as a shadcn-compatible registry. You install them directly into your project — no package to add, no version to track.

Prerequisites

Make sure you have a project set up with:

Next.js (App Router recommended)
Tailwind CSS v4
shadcn/ui initialized

Install a component

Use the shadcn CLI to add any component from the registry:

npx shadcn@latest add https://ui.justinlevine.me/r/github-stars-button.json

This will:

Download the component source into your project
Install any required npm dependencies
Add any shadcn registry dependencies (like button, card, etc.)

Manual installation

If you prefer not to use the CLI, you can copy the component source directly from the docs pages. Each component page includes the full source code.

Registry URL

The base registry URL is:

https://ui.justinlevine.me/r/

Individual component payloads are available at:

https://ui.justinlevine.me/r/{component-name}.json
